Detailed Description

Generic implementation of the Child concept.

The child class implements the Child concept in an operating system agnostic way.

Constructor & Destructor Documentation

boost::process::child::child	(	id_type	id,
		detail::file_handle	fhstdin,
		detail::file_handle	fhstdout,
		detail::file_handle	fhstderr,
		detail::file_handle	fhprocess = detail::file_handle()
	)			[inline]

Creates a new child object that represents the just spawned child process id.

The fhstdin, fhstdout and fhstderr file handles represent the parent's handles used to communicate with the corresponding data streams. They needn't be valid but their availability must match the redirections configured by the launcher that spawned this process.

The fhprocess handle represents a handle to the child process. It is only used on Windows as the implementation of wait() needs a process handle.

Member Function Documentation

postream& boost::process::child::get_stdin

(

)

const [inline]

Gets a reference to the child's standard input stream.

Returns a reference to a postream object that represents the standard input communication channel with the child process.

pistream& boost::process::child::get_stdout

(

)

const [inline]

Gets a reference to the child's standard output stream.

Returns a reference to a pistream object that represents the standard output communication channel with the child process.

pistream& boost::process::child::get_stderr

(

)

const [inline]

Gets a reference to the child's standard error stream.

Returns a reference to a pistream object that represents the standard error communication channel with the child process.

status boost::process::child::wait

(

)

[inline]

Blocks and waits for the child process to terminate.

Returns a status object that represents the child process' finalization condition. The child process object ceases to be valid after this call.

Remarks:

Blocking remarks: This call blocks if the child process has not finalized execution and waits until it terminates.
